1. add default option for tool [why] the tool will show help message if no option specified

[how] if no option specified, it will add '-h' as default option

2. fix undefined method 'empty' [why] the original data is defined nil, but not empty for my_email when execute answerback-email with no -e or -f, it will throw error as: raceback (most recent call last): 2: from ./answerback-email.rb:213:in `<main>' 1: from ./answerback-email.rb:184:in `send_account' ./answerback-email.rb:155:in `check_my_email': undefined method `empty?' for nil:NilClass (NoMethodError)

[how] use '.nil?' instead of '.empty?'
